Fig. 2 A diagram of a traditional
refrigeration plant where TGE is used
for ow in one direction only.
Fig. 3 A conventional split heat pump
system shown in cooling mode. This
system has two TGE thermostatic
expansion valves with xed direction
ow. An NRV check valve is placed in
series with each TGE to allow liquid
refrigerant to bypass when ow is
opposite the TXV xed direction.
Fig. 4 A heat pump system similar to that
in g. 3 but with a more compact
design, where the distance between
evaporator and condenser is very
short. This system has only one bi-ow
TGE valve metering liquid refrigerant
eectively in both directions.
Changeover is by means of a 4-way
valve.
A suction lter drier is often placed in
suction lines just before the
compressor. The normal ow direction
of TGE is determined by the primary
function, i.e. cooling or heating.
